Isolated Hemimegalencephaly (iHME) is a rare form of congenital malformation of cortical development.It is characterized by enlargement of all or part of one cerebral hemisphere. It typically presents with intractable seizures, mental retardation, developmental delay, contralateral hemiparesis and hemianopia. The patient was a five and half month's old baby girl who presented first with focal seizures at 10th day of life. No other physical or behavioral abnormality was noted. However, Initial EEG showed excessive sharp EEG transients more over the right hemisphere, repeated EEG showed spikes, polyspikes, sharps and slow wave discharges predominately over right hemisphere...

BACKGROUND: Diaphragm excursion is limited during respiratory maneuvers after a stroke. How the diaphragm is limited during reflexive coughs and affects the effectiveness of cough in stroke patients is unclear. This study aimed to measure reflexive cough strength by cough peak flow (CPF) induced by citric acid nebulization (2.8 mol/L), record diaphragm excursions during reflexive coughs in stroke subjects at risk of silent aspiration, and compare these values with those of stroke subjects without risk of aspiration or dysphagia...

Little literature is available on hemiparesis caused by vascular medullary compression, which may occur as a result of dolichoectasia of the vertebrobasilar arterial system. In this paper, we report a case of vertebral artery compression of the medulla oblongata in a 67-year old woman. The patient was hypertensive and developed hemiparesis and intermittent spasms for five years, which became worsened for one year. Cranial nerve MRI showed compression of the medulla oblongata by the left vertebral artery. Motor evoked potential (MEP) examination showed abnormal conduction of MEPs of bilateral toe abductors...

Patients can have more than one neurological problem, and sorting out acute from chronic disease can be challenging. The authors report a middle-aged patient who presented with ataxia, right hemiparesis, and abnormal nystagmus. Magnetic resonance imaging (MRI) showed a Chiari and an arachnoid cyst with brainstem compression that appeared to explain his abnormal examination. Shortly after admission, he was noted to have intermittent abnormal behavior and confusion. History from family revealed significant acute and chronic psychiatric problems that appeared to explain his abnormal mental status; this delayed the diagnosis of intermittent complex partial seizures...

We report the case of a patient with long-term history of hypertension, presenting with transient neurological disorders and severe graft failure several years after kidney transplantation. Cause of end-stage renal disease was hypertensive nephrosclerosis. Chronic hemodialysis lasted for 1 year. After transplantation and throughout follow-up, serum creatinine ranged from 200 to 230 μmol/L and maintenance immunosuppression included sirolimus and low-dose steroids. Six years after transplantation, the patient presented with right hip pain radiating to the lower back, transient aphasia, confusion, and hemiparesis...

BACKGROUND: Vascular compression of the medullary pyramid resulting in neurological compromise is rare, therefore, diagnosis is difficult and ultimately delayed. Most patients present with a combination of cranial nerve, autonomic, and/or motor and sensory dysfunction. Presentation with a single sign such as hemiparesis is rare. The low number of cases reported has made it impossible to define a standard treatment for this unusual disorder. CASE DESCRIPTION: Here, we present a patient with a progressive left hemiparesis due to compression of the upper medulla by the vertebral artery, which was treated with repositioning of the artery using a sling...

Adapting one's gait pattern requires a contribution from cortical motor commands. Evidence suggests that frequency-based analysis of electromyography (EMG) can be used to detect this cortical contribution. Specifically, increased EMG synchrony between synergistic muscles in the Piper frequency band has been linked to heightened corticomotor contribution to EMG. Stroke-related damage to cerebral motor pathways would be expected to diminish EMG Piper synchrony. The objective of this study is therefore to test the hypothesis that EMG Piper synchrony is diminished in the paretic leg relative to nonparetic and control legs, particularly during a long-step task of walking adaptability...

Opalski syndrome is a rare vascular brainstem syndrome which is accepted as a variant of Wallenberg syndrome. Opalski syndrome should be considered in acute conditions in which typical symptoms of lateral medullary infarct are accompanied by ipsilateral hemiparesis. Other brain stem syndromes are distinguished from Opalski syndrome by the presence of contralateral hemiparesis.

BACKGROUND: Hemiparesis after stroke typically results in a reduced walking speed, an asymmetrical gait pattern and a reduced ability to make gait adjustments. The purpose of this pilot study was to investigate the feasibility and preliminary efficacy of home-based training involving auditory cueing of stepping in place. METHODS: Twelve community-dwelling participants with chronic hemiparesis completed two 3-week blocks of home-based stepping to music overlaid with an auditory metronome...

[Purpose] Diffusion tensor imaging (DTI) has attracted attention as a method for determining prognosis following paralysis after stroke. However, DTI can assess the degree of damage to the corticospinal tract but cannot evaluate other brain regions. In this study, we examined in detail the prognosis of upper-limb function of the paralyzed side following stroke, using DTI and voxel-based morphometry (VBM). [Subjects and Methods] We studied 17 consecutive patients diagnosed with stroke, including hemorrhagic and ischemic types, who exhibited hemiparesis and were treated in our hospital...

BACKGROUND: Structural MRI and histopathological tissue sampling are routinely performed as part of the diagnostic work-up of glioma patients. Due to the heterogeneous nature of gliomas, there is however a risk of undergrading caused by histopathological sampling errors. MRI has limitations in identifying tumor grade and type, detecting diffuse invasive growth, and separating recurrences from treatment induced changes. PET can provide quantitative information of cellular activity and metabolism, and may therefore complement MRI...

BACKGROUND: 5-Aminolevulinic Acid (5-ALA) induced fluorescence is useful in guiding glioma resection. The extent of 5-ALA accumulation is beyond gadolinium contrast enhancement.(1,2) Supratotal resection may be achieved, potentially granting patients with better survival. We present our experience on 5-ALA guided glioma resection in Chinese ethnics. METHOD: Sixteen Patients ingested 5-ALA (Gliolan, Medas Germany) 20 mg/kg·m(2) 4 h before surgery. The tumor resection was guided by fluorescence with neurosurgical microscope...

Cerebral gas embolism (CGE) from the thoracic cavity is commonly associated with invasive procedures, and cases of spontaneous CGE are rare. A 78-year-old man presented with severe spontaneous CGE associated with combined pulmonary fibrosis and emphysema (CPFE). To the best of our knowledge, the comorbidity of CGE in a CPFE patient has not been documented until now. The patient became unconscious with left hemiparesis at approximately 2 a.m. Computed tomography scan revealed minute air densities scattered in the deep white matter of the right frontal lobe...
